Bionic self-clamping fruit tree scissors

Abstract

The invention discloses a pair of bionic self-clamping fruit tree scissors. A fixed blade, an intermediate plate and a branch clamping plate are fixed sequentially; a movable blade is connected with the outer side of the fixed blade; movable clamps are connected with the outer side of the branch clamping plate; a handle I and a handle II are fixed between the branch clamping plate and a blade laminate; a spindle-shaped spring is fixed between the handle I and the handle II; a twisting spring is fixed between the handle I and an intermediate plate layer; the movable blade is hinged to the handle I via a connecting rod II; a connecting rod I is connected with the handle II; a connecting rod III is connected with the connecting rod I via a circular slide block screw; the movable clamp I is riveted to the connecting rod III; the movable clamp II is riveted to the tail end of the movable clamp I; and a return spring is mounted between the movable clamp I and the movable clamp II. The pair of scissors simulates a clamping action of fingers of human during pruning, adopts a design structure of picking fruits or twigs by a single hand, can achieve a differential clamping trimming function, clamps the fruits while the twigs are cut off by the fruit tree scissor blades, and achieves single-hand fruit picking and branch pruning.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to a fruit tree shear with a bionic self-clamping function. Background technique [0002] In the growth management process of fruit trees, pruning and picking operations are essential links. Agronomically, the pruning of fruit trees can make the fruit trees form backbone branches and crowns and maintain a certain structure and shape, so as to achieve the purpose of ensuring high quality, high yield and stable yield of fruit trees. When ordinary fruit tree shears are used for pruning and picking fruit, one hand needs to cut the branches while the other hand needs to catch the fruit to prevent the fruit from falling to the ground and ensure the quality of the fruit. This will reduce labor efficiency and increase the labor of fruit farmers. Although the existing fruit tree shears (or pruning shears) with clamping mechanism on the market have realized the clamping functio...

AI Technical Summary

Problems solved by technology

Although the existing fruit tree shears (or pruning shears) with clamping mechanism on the market have realized the clamping function, because the clamping part is only simply attached to the blade and moves with the blade, the branches will be cut off, but the The phenomenon that the branch is not clamped; or the phenomenon that the branch is larger than the gap between the clamps and is clamped but cannot be cut

This kind of scissors is generally only suitable for pruning of branches that can be flattened or thinner, and the scope of application is limited
